What this B‑curve 32 A 2‑pole MCB does for a panel
The 2CDS252001R0325: A 32 A B‑curve MCB from the System Pro M Compact family. Two poles, so it switches both line and neutral in single‑phase sub‑circuits. The 6 kA Icn (service) breaking capacity is the figure that determines coordination with the upstream device; the 20 kA Icu (ultimate) confirms the device can clear a through‑fault once without damage, which gives the upstream protective device room to operate. Mounts on a 35 mm DIN rail. The 35 mm wide body leaves room for adjacent breakers in a multi‑pole grouping. IP20 for the main enclosure, IP40 at the terminals when the supplied gland plate is fitted — that matters in a panel with wash‑down risk or dust ingress.
